The Negative Effects of Statin Drugs on Cardiomyocytes: Current Review of Laboratory and Experimental Data (Mini-Review).

Statin drugs have long been used as a key component of lipid-lowering therapy, which is necessary for the prevention and treatment of atherosclerosis and cardiovascular diseases. Many studies focus on finding and refining new effects of statin drugs. In addition to the main lipidlowering effect (blocking cholesterol synthesis), statin drugs have a number of pleiotropic effects, including negative effects. The main beneficial effects of statin drugs on the components of the cardiovascular system are: anti-ischemic, antithrombotic, anti-apoptotic, antioxidant, endothelioprotective, anti-inflammatory properties, and a number of other beneficial effects. Due to these effects, statin drugs are considered one of the main therapeutic agents for the management of patients with cardiovascular pathologies. To date, many review manuscripts have been published on the myotoxicity, hepatotoxicity, nephrotoxicity, neurotoxicity and diabetogenic effects of statins. However, there are no review manuscripts considering the negative effect of statin drugs on myocardial contractile cells (cardiomyocytes). The purpose of this review is to discuss the negative effects of statin drugs on cardiomyocytes. Special attention is paid to the cardiotoxic action of statin drugs on cardiomyocytes and the mechanisms of increased serum levels of cardiac troponins. In the process of preparing this review, a detailed analysis of laboratory and experimental data devoted to the study of the negative effects of statin drugs on cardiomyocytes was carried out. The literature search was carried out with the keywords: statin drugs, negative effects, mechanisms, cardiac troponins, oxidative stress, apoptosis. Thus, statin drugs can have a number of negative effects on cardiomyocytes, in particular, increased oxidative stress, endoplasmic reticulum stress, damage to mitochondria and intercalated discs, and inhibition of glucose transport into cardiomyocytes. Additional studies are needed to confirm and clarify the mechanisms and clinical consequences of the negative effects of statin drugs on cardiomyocytes.
